# WHOIS

> Use this tool when you need to perform network information lookups, validate route objects, or analyze AS-SET hierarchies and contact information across multiple Regional Internet Registry (RIR) databases. It solves problems related to incident response, security research, and network engineering by providing raw WHOIS queries, contact card lookups, and AS-SET expansion. The tool accepts domain or IP addresses as input and returns network information, contact details, and validation results, making it ideal for use cases requiring accurate and up-to-date network data.

## Description

This MCP server provides network information lookup tools through WHOIS and RIR (Regional Internet Registry) database queries, supporting both RIPE NCC (Europe/Middle East/Central Asia) and ARIN (North America) regions with configurable RIR support. Built with Python using FastMCP, httpx, and aiohttp, it offers tools for raw WHOIS queries, contact card lookups for abuse/NOC/admin contacts, AS-SET expansion into concrete ASN lists with configurable recursion depth, and route object validation for BGP security workflows. The implementation includes TTL-based caching, async processing with proper timeout handling, and modular architecture separating RIR-specific functionality, making it valuable for network administrators conducting incident response, security researchers validating route objects, and network engineers analyzing AS-SET hierarchies and contact information across multiple RIR databases.
